CHURN.

Specification of Letters Patent No. 23,986, dated May 10, 1859.

To all whom it may concern:

Beit known thatI, JAMES O. MERRILL, of Chichester, in the county of Merrimack and State of New Hampshire, have invented a new and useful Improvement in Apparatus for Churning Butter, which I denominate Merrills Improved Oscillating Churn, and I do declare that the following is a full, clear, and exact description of the construction and operation of the same, reference be ing had to the annexed drawings, making a part of this specification, in which Figure 1, is a perspective view of the churn and apparatus for operating the same. Fig. 2, is also a perspective View of the same, presenting a vertical sectional view of the barrel of the churn and the dasher. Fig. 3, is a side View of the churn and apparatus. Fig. 4, is a viewof one of the dashers with its arm. Fig. 5, is a horizontal sectional View of the barrel of the churn, presenting a view of the upper surface of the dashers and their perforations. Fig. 6, is a view of the vibrating shaft.

The same letters in the several figures indicate corresponding parts of the apparatus.

A, is the foundation plank on which the barrel of the churn D, and the superstructure of the apparatus rest.

B, B, are the side pieces of the frame confined in position by the top cross braces C, C, (the latter shown in the drawings by dotted lines,) the center cross brace K, the bottom front braces H, H, and the bottom side braces I, I, confined at their respective ends by screws or bolts 07., n, &c. The brace K, is confined by the screws or bolts j, j.

J, is a guide bar projecting at the center two or three inches in front of the side pieces B, B, to which it is confined at each end by the screws or bolts 0?, cl; it is provided with two slots in which the alternate reciprocating dasher arms G, G, freely play, as seen in Fig. 1, of the drawings, the dasher arms being confined in the slots by the cap or button f, which plays on the screw or bolt 6, penetrating the guide bar J, and thus permitting the dasher arms G, G, to be removed or replaced at pleasure.

M, is a vibrating shaft supported by the cross braces C, C, the front axle p, of which is mortised into the vibrating lever E, as seen at b, Fig. 1, and the opposite axle p,

is mortised into the upper arm of the pendulum or oscillating lever L, as seen at b, Fig. 1.

F, F, are auxiliary levers confined at the ends of their upper arms to the vibrating lever E, by bolts or pins, as seen at 0, c, Fig. 1, on which they play freely, and at the ends of their lower arms they are confined to the dasher arms G, G, by the bolts or pins g, g, on which they also play freely.

i is a thumb screw passing through brace K, whose lower point rests upon the oblong lo lock Z, serving by the aid of the latter to keep in place the top or covering board of the churn, which is made in two pieces of semi-circular form, m, m, with slats or apertures for the reception and free reciprocating action of the dasher arms G, G, when the churn is in use.

N, N, are the dashers which are perforated with circular holes a, a &c., thereby causing the free and active agitation of the cream while undergoing the process of churning.

W, is a weight appended to the lower end of the oscillating lever L, to which is attached a handle it, by which the same is operated.

It is well known that the churning of butter, is one of the most laborious and severe operations of the dairy, when done by hand and by any of the machines or apparatus hitherto devised for that purpose. My improved apparatus relieves that operation of much of its tediousness and severity, and renders it comparatively light and easy, being adapted to the strength of a child.

The cream is readily placed in the barrel of the churn D, by raising the front half of the cover m which being replaced and pressed firmly down by the thumb screw 2', bearing on the block Z, the operator oscillates the lever L, which communicates the motion through the vibrating shaft M, the vibrating lever E, the auxiliary levers F, F, to the dasher arms G G thus roducin an alternate reciprocating action of the dashers N,

N, causing the latter to act vigorously on lieves the dasher arms G, G, and the churn may then be cleaned and prepared for future use.

Having above described the construction 5 of my said improvement, and its mode of operation What I claim and desire to secure by Letters Patent, is,

The arrangement of the oscillating lever L, and its Weight W, With the vibrating shaft 10 M, the vibrating lever E, the auxiliary 1evers F, F, and the alternate reciprocating dasher arms G, G, with their dashers N, N, constructed and operating substantially as above set forth, by Which the oscillating power of the pendulum is applied to the 15 process of churning butter.
